sPEcrrrcArroN 'forming pere ef Letters Patent No. 287,789, dated November e, less. l Applicatonfled December 13l 1882.v (No modela e l To all whom t may concern,.-

Be it known that I, GEORGE ARBOGAsT, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful l Improvements in Locomotive-Chairs; and I do herebyv declare that the following is a full, clear, and exact description thereof, reference being had'to theaccompanying drawings, andV to the letters of reference marked thereon,

Io which forma part of this specification.

This invention yconsists in certain improvements, as will' be hereinafter described and claimed, in the locomotive-chair described in I Patent No. 229,500, dated June 29, 1880.

i 5 In the drawings, Figure l .represents a perspective view of a chair constructed according to my improvements with the parts adjusted to-form a reclining-chair, and Fig. 2 represents a side elevation of such a chair with the 2o parts in upright position.

The improvements, as herein described, over the chair shown and described in the abovementioned patent consist, essentially, in constructing a chair with backv and leg-rest capable of adjustment at ,different inclinations, a pivoted or hinged foot-rest, adjustable ar1n` rests, and in rendering the sprocket-and-chain supporting and hand-crank standards adjustable toward or from the chair-back.

3o A represents vthe back, VB the seat, C the 3 5 ation of the devices.

The rear end of each arm-rest D is provided with a thumb or set screw, d, which is passed .through said slot, in order vthatthe rear ends of. said arm-rests may be raised or lowered, and

4o thus vertically adjusted as itis desired toinipart to said arm-rests a greater or less degree of angularity. The slot b also permits of the changing ofthe inclination of the back relatively to the leg and foot rests;

v E E represent slotted brace-bars pivotallyA secured, one on either side of the chair, at their upper ends to the arm-rests. These brace-bars, through the medium of thumbscrews e, adjustably connect the arm-rests to f back leg-'rest standards, F, and arm-rests mayY b e rigidly held in a vertical or more or less inclinedposition. 1 y e To the front ends, of the arm-rests ,I attach by screw-nutf one end of a slotted link, G, whose other end is attached to the standards f the hand-crank standards Hv can be drawn rearwardly or pushed away outwardly, and by tightening said nut clamped firmly at any desired inclination, so as to bring the cranks I in the most convenient position for being actuated by the occupantV ofthe chair.

rIhe foot-rest D is pivoted at g within or between the leg-rest standards F, in order that such foot-rest may be folded back upon the son easily getting into the chair. Y

As will be observed on'reference to Fig. l, this chair can be readily converted into ai reclining or semi-reclining chair, or, as shown in Fig. 2, into a straight-back chair, with the `foot-rest in a horizontal position. 1

in their foremost position of adjustment; but they can be readily brought back to astraight position, or to any rearwardly-inclined angle, bythe occupant of the chair, who'would simply have to loosen the screw-nut, draw the standards II back, and then again tighten the nut.' Similarly, the set or thumb screws for from to adjust such parts to the degree of inclination desired. n

` 'Ihe standards H are bifurcated, as shown, and are sleeved upon the axle of the drivewheels K; andV L represents asprocket-wheel mounted upon the hub of each wheel K; and

naled within vertically-slotted brackets h in the upper part of the standards H, and having a crank I, by which said wheel M is turned. The endless open-linked chainl N travels around the sprocket-wheels LM, as in the before-mentioned construction.

"The obj ect of the slot h is to permit of chains N of different lengths being used; or, should H of the hand-crank-I. By loosening this nut- M represents another sprocket-wheel, jour,-

leg-rest( and out of the Way, tolpermit of a per- InFig. 2the handcrank standards are shown clamping the arm-rests, back, and leg-rest in position are within easy reach of the occupantl ofthe chair, and can be readily operated thereo one or more links of the chainbecome broken, roo

"n '5o the'lower end of the back, in order that the by reuniting` the loose ends and lowering the sprocket-Wheel M said reunited chain can again be used.

O represents a caster-Wheehwhich is pivoted in a curved bifurcated stock, I), having,` a bracket, Q, for supporting the rear portion of the chair.

Having thus described my invention, what I claini therein is l. The combination, in an adjustable chair, of the slotted back-frame a, arm-rests D', adjustably secured at their rear ends Within the slotted frame a, and the slotted brace-bars E, pivotally secured at their upper ends to the arm-rests, and adjustablyconnected at their lower ends by thumb-screws to the lower end of the back, substantially as and for the purpose set forth.

2. In a locomotive-chair, the combination of the arm-rests D', hand-crank standards H,

- slotted link G, attached at one end to said standards, and adjustably secured at the other end by nutf to the arm-rests, crank I, chain N, sprocketwrheels L M, and drivevwheels K, substantially as and for the purpose set forth.

3. A loconiotivechair having adjustable back, and arni and leg rests, sprocket-wheels L and M, cranks I, bifurcated standards H, and slotted links G, substantially as and for 3o the purpose set forth.

l. A chair having a vertically-slotted back, arm-rests adj ustably secured at their rear ends within said frame by set-screws, slotted bracebars pivotally secured at their upper ends to the arm-rests, and adj ustably connected at their lowerl ends by thumb-screws to the lower end of the back, and a leg-rest pivotally secured at its upper end to said arm-rests, substantially as and for the purpose set forth.

5. A locomotive-chair having a verticallyslotted back, armrests adjustably secured at their rear endswithin said frame by set-screws, slotted brace-bars pivotally secured at their upper ends to the arm-rests, and adjustably connected at their lower ends by thumb-screws to the lower end of the back, and a leg-rest pivotally secured at its upper end to said armrests, hand-crank standards H, crank I, slot ted link G, chain N, sprocket-wheels L M, and drive-wheels K, substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my invention I affix my signature in presence of two Witnesses.
